What does a wall adapter for the iPad have to do with a PC or a Mac ?. The adapter fits into a electrical outlet.
Hence my confusion about the ruckus. Use a 500mA USB port, take longer to charge; use the 10W power supply that comes with the iPad, charge faster. Yeah it will suck >2A if you can feed it that fast - GOOD!
What's the issue? Sounds like the iPad 1.
Possibly stupid first-world problem:
Ever since the stories surfaced of iPhones blowing up due to battery expansion when they're left plugged in for extended periods, I've not felt good about plugging in the iPhone overnight. Not a huge issue, as I can plug it in in the morning and there's enough juice to get it through a day. But it seems to fully charge the iPad you pretty much NEED to charge it for a long while, and that means overnight. So, how do I know that it's safe to do so?
I recall there was that one fireman dude who had to throw his out a window... yikes!
People get hit by lightning more often than there are exploding iPhones. Just about anything is more likely to go wrong than that
Install some smoke detectors (you should have those anyway) and forget about it.
A Prius has a helluva lot more space to put high-power charging systems AND requisite safety gear (insulation, explosion containment, ...). Yeah they could do that with an iPad, but then you'd be carrying a 1 foot cube around.
Are you sure about your lightning vs iphone explosion statements?People get hit by lightning more often than there are exploding iPhones. Just about anything is more likely to go wrong than that

If so, it would be nice to see the facts.
Here's one from recently as last week.
A quick search will turn up hundreds of iphones melting, smoking & exploding.
Time will tell if the iphone battery issue has migrated over to the new iPad.

Wifi syncing is only useful on small changes. My videos have been messed up many times because syncing over night with a 64GB ipad is just to slow. Besides how do you select different apps and videos if you dont go to your PC/Mac to select them?
The problems begin when new iPad's battery continues to lose charge even while plugged into the provided wall charger.
I've only noticed this when watching videos with maximum brightness. Not a big deal but something to consider.

Ha, this is a funny thread, all this talk about the amperage to kill people and start cars. As a biomed engineering type, I'll just say that it's all relative as to what it takes to kill, skin resistance being your friend.
Regarding these apple products. USB stock spec is 500ma. When the iPhone came out it drew more, suddenly the old iPod chargers wouldn't charge them. Then the iPads came out along with a new 2.1A capacity charger, who cares? Use an external charger, sheeze, it's so much faster.
Bigger capacity batteries can charge fast if you can give them higher charge rates, more current. Heck with the right equipment I charge lithuim batteries in 15min. Since the current Apple stock charger is rated at 2.1A it should be no suprise that the larger iPad3 draws as much as the supply can deliver and takes longer than the iPad2 since it's 70% larger.
The bigger question in my mind is, will someone produce a compact charger with something like a 3A rating as I think the iPad3 just might accept a higher charge rate. I don't use the stock chargers, opting for a more compact unit with dual ports, each rated at 2.1A. My iPad3 is slightly warmer when running but as noted by others with the cool I/R measurement gear, it's maybe 10 degrees at best, in that one corner again, not a big deal.
I returned my ATT iPad3 on day one and swapped for a Verizon version, specifically for the free personal hotspot. It is SMOKING fast on 4G over 10MB/sec UP and Down!! Much faster than ATT would have been anyway, shame on ATT for not playing ball, their loss, I'm gone!
Edit, I really do know a lot about lithium batteries, and yes, they can be dangerous and can burn like a road flare. But it's really really rare. Out of MILLIONs of units you read a horror story about 1 failure. Virtually all consumer lithiums are monitored with a integrated charge controller/monitor chip. This chip's sole purpose in life is to keep the battery from over charging and over discharge as either condition will destroy the battery. Used this way they are very safe, I leave all my lithium powered devices, especially ones with "soft" power buttons (almost all Apple products) since they draw a small amount of power even when off. Leaving a lithium powered device dead will destroy the battery unlike other technologies like Nicad, NickelMetal etc.

I wonder... I know that this has to be a rare thing or there'd be hell to pay, but I'd love to see the numbers. That is 1 in 1000000? 1 in 1000? What is it? How often to batteries and/or the circuitry that controls how they charge fail with potentially dangerous results?
I am going to side with Aiden on this. Whenever we need a computer for data collection or device automation, there is NO Apple option. You need a PC and you need x86 and you need windows (of various eras).Of course, Aiden, here it goes:
Inferior PC < Superior PC < Mac
Once you collect that data or set up that automation, the device to analyze or control it is a Mac, but, let's at least be honest, that's 10% of the installed base.
We need a headless Mac with Wintel and legacy ports. Just one. That would increase the installed base [to] a full 30% IMHO.
Just Rocketman
Edit: I have been beating this dead horse for years . . .
Steve would hate me for saying it and would in no way go along. That's why we have Tim to increase market share from 6% to 30% and know how to actually fulfill that. Scary-cool! (far better than insanely great and a $1000 stock price AFTER a 4:1 stock split . . .)

I let my iPad 3 run down to completely dead Friday, and plugged it into my 2007 iMac USB port to trickle charge back to 100% (I was busy all weekend, didn't need the iPad). It took over 24 hours to go from dead to 100% charged using that 500mA USB port.
Agreed. Regardless of whether a buyer has a computer (Mac or otherwise) with high-power USB ports, the fastest way of charging the iPad is with the INCLUDED 10W charging cable. So how is it that they conclude that Apple does not care? What is Apple supposed to do, supply a logic board for non-Mac computers to replace their existing motherboards with ones that have high-power USB ports? Or maybe include a free Mac with every purchase?
I was referring to charging through low-power USB ports common in Winblows PCs...
The same USB standard ports that most Apples have, by the way.
And, it seems that only one USB port on an Apple can run at high-power.
Recent Apples and PCs support the high-power USB standard on a subset of the available ports - what is the difference in "superiority"?
...and saying "Winblows" demeans your argument. Don't resort to insults that a junior high school student would use.
I think you are going to the other extreme. It is an issue. I use my iPad for business most of the day. I could use my iPad2 all day and have 30% or more battery left. My iPad 3 will die in 4-5 hours MAX. Thats not so bad but the real problem is that I can't even keep up with charging it. It charges SOOOO SLOW that it is a battle to keep power. Then If I plug it in at 10pm and unplug it at 5:30 or 6am, its only charged to 97%. Needs another hour. The problem is that it takes longer to charge the battery than it does to drain it.
That IS a problem that Apple should find a way to deal with it. (faster charger?)
i love my new ipad. i leave it charging overnight and its always at 100% when i wake up. after a full day of pretty heavy use, i still find myself with a good 25-30% left. no problems here.
i was curious tho, IS it possible to manufacture a charger that would charge the iPad faster? im pretty clueless when it comes to these techie kind of things... is the iPad limited to the wall charger provided by apple? or could someone sell a charge that would deliver more power to the device? without damaging it?
i dont know how that all works... for those instances where we might only have a few hours to charge...

I think there is something seriously wrong with your iPad if you're only getting 4-5 hours of usage.
No it isn't. A few milliamps across the heart might kill you. AA batteries are constant voltage sources and have very limited power output and thus will never be able to kill you. A car (or marine) battery COULD kill you if you manage to lower the resistance of your skin with water or sweat.
You are right that this isn't news though.
The iPad is designed to only draw so much current. After that amount it won't do you any good to use a higher output charger.
Soo... If you have a changer that was capable of 1.5 Milliamp output it would charge slower then a 2.5mA charger. However if you had a charger that output 10 Amps it would not charge any faster then the 2.5mA.
